Hello,

I'm using the MiniProg3 (!https://www.cypress.com/documentation/development-kitsboards/cy8ckit-002-psoc-miniprog3-program-and-...  ) programmer to program my Cyble 012011-00 (!https://www.cypress.com/file/212456/download) module with EZ-Serial hex file (!https://www.cypress.com/documentation/software-and-drivers/ez-serial-ez-ble-module-firmware-platform).

I'm using PSoC Programmer software to program the hex file to the board, which does work as seen in the pictures. However, when I then try to connect it with my RX & TX pins to view the output in a terminal, it doesn't output anything. The documentation of EZ-serial says that it should output a system_boot event upon reset/power on. When I reset the module, the event output is not displayed. Sending commands, such a "/PING" is also does not provide a response.

I'm pretty clueless about what I am doing wrong at this point. Any help would be greatly appreciated!

Kind regards,

Toink

Hi Toink,

The power supply(1.8 - 5.5 volts) should be connected to VDD as well as VDDR pins. Please check page number 10 of the module datasheet. I guess you have missed this connection. Please check and update.

Please ensure that the power supply you provide is noise free.

Thanks

Ganesh

Hi,

What is the terminal viewer that you are using? Please ensure that you have selected correct COM port in the terminal and also in the port settings. The default port settings are 115200 baud, 8 data bits, no parity, and one stop bit. Flow control is supported, but must be specifically enabled if desired.

Are you using custom board? If yes, please attach CYBLE-012011-00 connections section your board schematic once.

Please check whether you are using P1.4 and P1.5 pins for UART. The serial firmware used UART present on P1.4 and P1.5 . Please check the below image for other peripheral connections:

Hi GaneshD_41​ ,

I have been using Putty AND also tried a python script with the pyserial module, with the default settings (115200, 8 data, 0 parity, 1 stop).

I am solely using the Cyble 012011 board (see attached). As seen in the picture, the blue and yellow wires are connected to P1.5 and P1.4, these are then connected to a FTDI232 board that I then open with Putty/Pyserial.

I have verified that the FTDI232 board works.

Kind regards,

Toink

Hi Ganesh,

Thank you very much! This was indeed the solution. I think I overlooked this in the datasheet...

Thanks,

Toink.
